<p><strong>NEMA 17 Mounting Holes</strong></p>
<p>To clarify, the 68 oz.in Stepper Motor uses the NEMA 17 mounting holes. The motor size of this stepper motor is slightly smaller than what you would expect for a NEMA 17 motor size width and length. Try looking at the datasheet for more information about this motor&rsquo;s dimensions.</p>M-Short on ROB-10846 - Stepper Motor - 68 oz.in (400 steps/rev)M-Shorturn:uuid:c089da91-5d26-a49f-be1b-29440a50fb0d2016-06-06T10:25:33-06:00<p>For those curious as to how our stock works our resellers do buy directly online.

It works great with a little cooling at 1.4A@19.5V off of a Smoothieboard. Retracts are consistent with no skipping or stalling at 4mm @ 50mm/s. Because of the smaller step angle than typical 3D printer steppers, it&rsquo;s not a good choice for geared extruders.

The point of the driver is to provide the power to the motor in a way it can use (for a stepper its alternating pulses). This motor will pull up to 3A when it stalls, no more (in theory, always give yourself some extra room). You need to make sure your stepper driver and the power supply can handle at least 3A. It doesn&rsquo;t look like that driver will.

Principally microstepping is working: I have to trigger the the correct amount of steps to get it turn the desired angle and I also can hear that the motor is changing its sound when I shift it by a single step (in microstepping mode). So the driver seems to work, but the motor does not turn every microstep, but just every fullstep. E.g. in the 1/8 microstepping mode I have to trigger 8 steps until the motor moves for the first time. But then it travels the correct 0.9 degrees. The same problems seems to appear for every other microstepping value, so I need to trigger 4 steps in the &frac14; mode to see it turning. In fullstep mode of course everything works as expected. Does anyone have an idea about this, or do I just don&rsquo;t grasp it?

I made an acrylic adapter for one (saw and drill press, no laser cutter) that I mounted to a channel piece and just elongated the mounting holes on a dual flat bracket to mount the other. Both techniques worked well. The former is the more elegant solution. The latter is considerably easier. Spacers are required between the motor or adapter and the Actobotics piece. The biggest challenge is getting everything aligned. I use a &frac14;-20 screw plate as a drilling template for making Actobotics compatible components. It is steel, not aluminum so it holds up well. And once you drill two holes, you can physically screw it in to your piece to hold alignment.</p>rubot on ROB-10846 - Stepper Motor - 68 oz.in (400 steps/rev)ruboturn:uuid:489b4c5c-df93-331e-38c4-59e5f8ce4e6a2014-02-02T16:46:44-07:00<p>I was also excited about the actobotics product line but then i couldn&rsquo;t seem to find any stepper motor mounts.

Want to use this particular one to shuffle some candy pieces around. I&rsquo;m using the Big Easy Driver. I&rsquo;m controlling it with an Arduino (on a breadboard at 16 MHz). The pulsing routine looks like this:</p>
<pre><code>#define CLOCKWISE LOW
#define COUNTERCLOCKWISE HIGH
void stepperSteps( long n ) {
digitalWrite( DIR_PIN, n &lt; 0 ? COUNTERCLOCKWISE : CLOCKWISE );
digitalWrite( ENABLE_PIN, LOW );
n = abs( n );
for( ; n &gt; 0; n-- ) {
PORTB |= _BV(PINB1); // WAY faster than digitalWrite
delayMicroseconds( 50 );
PORTB &amp;= ~_BV(PINB1);
delayMicroseconds( 50 );
}
digitalWrite( ENABLE_PIN, HIGH );
}
</code></pre>
<p>I ENAble the board, set direction, pulse using direct bit manipulation to get it as fast as possible, then unENAble the board. I tuned the current to the motor and all seems to be pretty happy.</p>
<p>The BED docs say pulses should be 10 µsecs. If I do that, the motor stutters. I assume because there just isn&rsquo;t enough time between edges. 50 µsecs is the sweet spot I&rsquo;ve found. Upwards of 100 µsecs or longer and the motor stutters again. When the motor stutters, I try upping the current thinking maybe it needs some help holding between pulses. That just makes the motor and the BED super hot (chip gets to 150ºF, motor is barely comfortable to hold) and generally doesn&rsquo;t help the motor move well at all. At 50 µsecs, the chip temperature drops to 80-ishºF.</p>
<p>Anyone have a solid reason why 50 µsecs would be the sweet spot for making everything move smoothly?

NO your easy driver cannot correctly provide enough current for this motor. (Just because it says 2Amps for the new version, that assumes proper thermal managment, AKA cooling). The reason it seems to turn on and off is you are overheating the easy driver. This motor must be limited to 1.7 Amps from your voltage source by the stepper driver. If you start out with 12 volts or higher, the 1.8 Ohms of the motor coil is going to result in more than 1.7 Amps. But that&rsquo;s why we use switching stepper driver that PWMs the output of the H-bridge and limits the current. The thing to keep in mind too is that it&rsquo;s an inductor and thus that 1.8 Ohms is not the complete picture. When the motor moves, we turn off and on the coils and that frequency too affects the complex impedance of the coil. Thus the the apparent voltage across the coil changes to result in the same current as the motor speeds up or down. This is why we want the higher source voltage, to ensure we have enough headroom to attempt to keep the same current (and thus magnetic strength which creates the torque). Again, the key here is that the stepper drive actively limits the current via PWM to the motor coil. That means the driver will kick off a fair amount of heat as the energy must go somewhere and the 1.8 Ohms of the motor isn&rsquo;t going to disipate much. When you turn down the current potentiometer of the stepper driver to a level where it can survive (most say about 1 Amp or less on an easydriver) then you will get about half the rated torque at best. You really need an industrial rated driver (2 Amps or more and heatsinked) to properly run these motors at spec. Again, to be clear, while you might slap a heasink onto the easy driver and add a fan, it may not be enough to properly run this motor at 1.7 Amps in all conditions. You can turn the current down, but then you do not get the rated torque.</p>Penitent_Tangent on ROB-10846 - Stepper Motor - 68 oz.in (400 steps/rev)Penitent_Tangenturn:uuid:e7b58b67-3023-cb09-da51-92de0b56cba12012-10-14T21:37:26-06:00<p>I don&rsquo;t know if i should be posting this here or on the Big Easy Driver Page, but i&rsquo;m hoping somebody will be able to provide me with some insight. I have been able to get it running using the example provided on Brian&rsquo;s website. The issue i am having, is that the motor will only run smoothly when the current is being limited much lower than what the motor is capable of. When i adjust the current limit higher the motor will keep losing power entirely (i.e. the shaft can be freely spun until it starts spinning again). Is this an issue with the supply i am running it off of? The power supply i am using is a 19V supply rated at 4.7 amps.</p>Customer #217718 on ROB-10846 - Stepper Motor - 68 oz.in (400 steps/rev)Customer #217718urn:uuid:c98df1f5-bfee-1d2c-9b99-71a09f1933452012-09-29T03:43:10-06:00<p>Ditto - I&rsquo;m sweating on these also.</p>Customer #363551 on ROB-10846 - Stepper Motor - 68 oz.in (400 steps/rev)Customer #363551urn:uuid:309e0a32-f506-3b1b-5146-88e1f8556f2e2012-09-28T17:33:33-06:00<p>Anyone knows when they will be in stock again ?</p>LineKernel on ROB-10846 - Stepper Motor - 68 oz.in (400 steps/rev)LineKernelurn:uuid:06851f50-20e3-9bf2-612f-ce72d0044e8b2012-09-08T14:55:54-06:00<p>basicaly , just take care that your driver intensity specs are respected (for example easy driver is a no-go)
